Here's another easy crock pot recipe.

Chicken Cacciatore

2 pounds boneless skinless chicken breasts or thighs
1/2 a large or 1 whole small onion
1 green bell pepper
1 12 oz can tomato paste
1/2 cup red wine (I use Merlot)
1 tsp dry italian seasoning
2 - 3 garlic cloves

Slice the onion into half rings and then cut in half again
Slice the pepper into strips
Cut the chicken breasts into serving pieces (I usually cut each piece in half depending on the size of the breast.
Smash and peel the garlic cloves, do not chop.
In a bowl mix the tomato paste, wine, garlic cloves and italian seasoning.

Place the onions and peppers in the bottom of the crock pot, then add the chicken pieces on top of the vegetables.
Pour the tomato paste mixture over the chicken, spreading it evenly.

Cook on low 6 - 8 hours.
Serve over your favorite pasta (i use spaghetti since it makes a thin sauce). 
With a salad and garlic bread it makes a easy meal.
